EA-PU 10360-480 6U WC Water-Cooled Programmable DC Power Supply

The EA-PU 10360-480 6U WC is a water-cooled, high-power programmable DC power supply unit from the versatile PU 10000 series. It delivers a robust 60 kW of autoranging output power across a wide range of 0-360 V DC and 0-480 A DC, making it an ideal choice for demanding industrial and R&D applications. Featuring exceptional efficiency up to 95.8% and active Power Factor Correction (typical 0.99), it ensures energy-saving operation and minimal grid pollution. The unit accepts a three-phase AC input (380-480 V ±10%, 45-65 Hz) for global usability. Advanced digital regulation with 16-bit resolution supports CV, CC, CP, and CR modes with fast crossover, excellent stability (CV load regulation ≤0.05% FS), and dynamic response (CV rise time ≤10 ms). For system scalability, it integrates a galvanically isolated Master-Slave Bus and Share-Bus, allowing seamless parallel operation of up to 64 units to create systems up to 3840 kW. Comprehensive built-in interfaces (USB, Ethernet, Analog) and a wide array of optional industrial communication modules (CAN, Profinet, EtherCAT, Modbus, etc.) enable easy integration into automated test stands. The included water cooling (WC) option ensures optimal thermal management, reduced acoustic noise, and reliable performance in high-power-density or continuous operation scenarios such as fuel cell simulation, electrolysis for green hydrogen production, electric vehicle component testing, and solar array simulation.

Key Features
